Description

Technical Field

[0001] This utility model relates to the field of LED lamp bead technology, specifically to an LED lamp bead connection structure. Background Technology

[0002] The connection structure of LED beads refers to the overall structural design that connects individual LED beads or bead modules with components such as circuits, heat dissipation parts, and support structures to achieve circuit conduction, energy transmission, heat dissipation, and mechanical fixation. Its core objective is to ensure stable circuit conduction, efficient light output, effective heat dissipation, and adaptability to the installation requirements of different application scenarios such as lighting fixtures, displays, and indicator lights.

[0003] Existing technology publication CN220287362U discloses an LED bead connection structure, including an LED bead and wires. Two leads of the LED bead are respectively soldered to two wires. A hot melt adhesive is placed between the two leads of the LED bead and the soldered wires. After heating, the hot melt adhesive connects to the leads and wires as a whole. A heat shrink tubing is fitted over the connection point between the LED bead's leads and the wires. The LED bead connection structure obtained by this invention utilizes hot melt adhesive placed between the two leads of the LED bead, and during heating, it can connect the two leads of the LED bead to the soldered wires as a whole, preventing relative displacement during use, thereby improving reliability.

[0004] However, there are many types of existing LED chip connection structures. One type is the through-hole LED chip, which has two metal pins at the bottom. During installation, the pins are soldered to the copper foil circuit on the PCB board by wave soldering or manual soldering through the pad holes on the PCB board to form an electrical connection. Surface mount LED chips are also usually connected by soldering. However, this type of LED chip connection structure is not only difficult to install, but also requires desoldering and resoldering when replacing, resulting in low maintenance efficiency and inconvenient operation. Therefore, we propose an LED chip connection structure. Utility Model Content

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: an LED bead connection structure, comprising a bead shell, an anode support and a cathode support embedded inside the bead shell, a limiting ring integrally formed on the outer side of each anode support and cathode support, a snap-fit ​​connector integrally formed at the bottom end of each anode support and cathode support, a connecting cap snapped onto the outer side of the bottom end of each anode support and cathode support, a connecting port opened at the top of the connecting cap, a snap-fit ​​interface opened on the inner wall of the connecting port, a cathode bracket installed at the top of the cathode support, an LED chip installed at the top of the cathode bracket, and a connecting wire welded to the top of the LED chip.

[0014] (III) Beneficial Effects

[0015] This utility model provides an LED lamp bead connection structure, which has the following beneficial effects:

[0016] (1) This LED bead connection structure, through the setting of an anode bracket, a snap connector, a cathode bracket, a limiting ring, and a connecting cap, allows the operator to insert the anode bracket and cathode bracket into the through-hole of the circuit board when using the LED bead connection structure. The limiting ring on the anode bracket and cathode bracket presses against the top of the circuit board. Then, the connecting port of the connecting cap is sleeved on the outside of the anode bracket and cathode bracket. At this time, the snap connector of the anode bracket and cathode bracket can be snapped into the snap interface. At the same time, the connecting cap presses against the bottom of the circuit board. When replacing the LED bead, the operator only needs to pull out the connecting cap to pull out the anode bracket and cathode bracket. Then, the same method can be used for installation. In this way, the LED bead can be installed and removed without soldering, which not only simplifies the installation difficulty but also improves the maintenance efficiency.

[0024] Furthermore, the bottom of the lamp bead shell 1 is integrally formed with a lamp holder 2. Both the lamp bead shell 1 and the lamp holder 2 are made of epoxy resin, making the lamp bead shell 1 and the lamp holder 2 more robust and durable, and less prone to damage.

[0025] Furthermore, the connecting wire 12 is welded to the anode bracket 3, and current can be transmitted through the connecting wire 12, so that the LED chip 11 can operate normally.

[0026] Furthermore, a circuit board 6 is installed on the outer side of the anode support 3 and the cathode support 4 below the limiting ring 5, so that the LED beads can operate normally.

[0027] Furthermore, both the anode support 3 and the cathode support 4 are made of metal. The outer surfaces of the anode support 3 and the cathode support 4 are smooth. The anode support 3 and the cathode support 4 made of metal are more robust and durable and less prone to damage.

[0028] Furthermore, there are two connecting caps 7, which are the same size and shape. The connecting port 8 of the connecting cap 7 is sleeved on the outside of the anode support 3 and the cathode support 4. At this time, the snap-fit ​​connectors 301 of the anode support 3 and the cathode support 4 can be snapped into the snap-fit ​​interface 9, which facilitates installation.

[0029] Working Principle: After installation, first check the installation, fixation, and safety protection of this utility model. When using the LED lamp bead connection structure, the worker inserts the anode bracket 3 and cathode bracket 4 into the through-hole of the circuit board 6, so that the limiting rings 5 ​​on the anode bracket 3 and cathode bracket 4 press against the top of the circuit board 6.

When replacing LED lamp beads, the worker only needs to pull out the connecting cap 7 to pull out the anode bracket 3 and cathode bracket 4. Then, the installation is carried out in the same way. This completes the use of this utility model. This utility model has a simple structure and is safe and convenient to use.
